Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 511548, here are decompositions:

7 + 511541 = 511548
29 + 511519 = 511548
41 + 511507 = 511548
61 + 511487 = 511548
71 + 511477 = 511548
101 + 511447 = 511548
109 + 511439 = 511548
131 + 511417 = 511548

Showing the first eight; more decompositions exist.
